Longitudinal, strips. 24,- of asbestos, are secured to sheet. 18.. and, extend.- between alternate. stripskiz, in such-,amanner as to. define a' tortuous passage 26"having an en.. trance 2t'and an exit 331 A plurality of bafile formingasbestos. blocks 321 are secured to the sheet i3b'y asbestosv cement to slow the passageojf airjthrough passageway 25.1 The blocks 32" extendupwardl'y fromth'e sheet. 58 substantially thesarne. amount as the. strips. 2%; 22; and't ii A metallic sheet, 35, preferably of aluminum, extends over the sheet Itl and the blocks and stripsi'i, 2.2;and. 24. Thiametallic sheet, as, forms a flooring and extends from: wall to wall. of ,the.room..l2.-

Means is provided fordrarvin air from-thew exit 38- of passagewayit andxfor:directingrair: into and throughthe passageway by Way0fnthep entrance 28 of the passageway. This means comprises a heat producing assembly 35 supported on a mount, the latter being in the form of an open substantially rectangular angle iron frame 38 whose ends are removably secured to the opposing faces of a pair of wall joists 40 by fasteners 42.

The lower section M of a housing member extends upwardly into the opening in frame 38 and is formed with laterally projecting ears 46 that are removably secured to the side portions of the frame 38. The bottom wall of housing forming section 44 is formed with an inlet spout 48 and an outlet spout 56 that extend into the exit 30 and entrance 28, respectively. The upper section 52 of the housing member is removably secured to section 4d, whereby a heating element 54 maysection line 6.5'

be inserted into or removed from the housing member.

Heating element 54 comprises a pair of rectangular strips or plates 56 that are centrally transversely slotted to permit the plates to be engaged with one another. The ends of the plates 56 are provided with apertures 58 that receive heating coils 60 whose ends are connected to two conductive prongs 62 attached to an offset 64 of one of the plates.

The bottom wall of the section 44 is formed with a central opening in which a socket 66 is positioned to receive the prongs 62. An outlet cord 68 extends from socket 66 and to a suitable source of electric current.

A U-shaped motor mounting member ID of channel shaped cross-section is removably secured to frame 38 and receives the flanged base plate 12 of an electric motor 14 whose armature shaft 16 extends into the housing member to support an impeller blade 18. The member is preferably of two piece construction with its base portion 80 of resilient material to cushion the vibration of the motor.

In practical use of the present invention, the switch 82 to the motor and the heating element is positioned on a wall of the room i2. When the switch is moved to its circuit closing position, the heating element will be energized and the blade 18 will draw air from the exit of the passage and will direct air over the heating unit and through the outlet spout 50.

A bimetal member may be connected to the heating element or a suitable thermostat electrically connected therewith, whereby the room area may be heated to a predetermined temperature. Cooling coils may replace the heating unit and be connected to a refrigeration system to permit cooling of the room area in warm weather.
